To all whom it may concern:

Be it known thatvI, FRANK A. Se'HUnTz, a citizen of the United States,and resident of Chicago, county of Cook, andv State of have inventedcertain'neW and useful Improvements in Lamp-Burners, of which thefollowing is a specication, and

`Which are illustrated in the accompanying drawings, forming a partthereof.

The inventionY relates to burners for switch and signal lamps, and whichhave come to be known in the art Yas long-time burners,theircharacteristic feature being that they [will produce a-comparatively sma'll flame point liame.

-: for a long` The present invention is an improvement' f.

'on the burner forming -Patent No. 851,827, of April 80,; 1907, issued lstem; or other means, to :a lamp font. not shown, and there 1s employedthe usual tv icki period `-without trimming.

the subject of Letters on the application of John'A. Mosher, which wasintended to. producea round or pencil The object of this invention is tosecure., in a burner of this type, a lat'flame and one f vWhich'willproduce a greater degree of'illu- 'I Inination; and It consists 1n thestructurel hereinafter described, and which is ,illustrated' in theaccompanying drawings, in Whichi Figure l is a plan view of the burnerWithout chimneyor chimney-holder; Fig. 2 is a side elevation of theburner, the chimney and chimney-holder being in. central Yverticalsectio'ngf'and Fig. .3 is a central vertical section bf the burner andWick-tube alone.

The burneris carried by the usual casing i 10, adapted to besecured by.a threaded 5 raising mechanism, the spindle of which isA represented atl1. --Thefvvicktube l2 extends tion, a Wick-tube, an ,oblong cup-mounted on through the casing l0 on its vertical`aXis,.l

--and ispreferably round to accommodate a i Wick 13 of the samefforrn.,The burner s proper is inthe form of anoblong cup 14',

' -endof the tube 12, thevaperture being sur l5 which lits upon the tube.as a sleeve.

Theends o f the cup flarel outwardlyand are scalloped, as shownin Fig.1,' thereby l providing a"central grooveor channelv ,16 f

flanked by oblique Walls 17, 1S, eachl of .which isl provided adjacentitsA lower end with an airport 19, 20. The-sides 21,22, of

the cup are substantially parallel Vand ar'efl .practice the Wick. 13 israised so 'that' upper end is above the bottoms of the apen-'- tu'res23, 24, and above the ports 19, 20. '.'The' action ofthe channelsl 16,

-l cut away or recessed fromabove to form in each a V-shaped aperture23,24, which eX`= Its tends Well. to the bottom of'th'e clip.

burner is preferably providedxwith a chimney-25, seated upon a gallery26, and held in place by spring fingers 27.-

The flame which normally',v being from a round Wick, would be pencilshaped, is spread by the burner to flat form, 'its edges 'following upthe channels 16, 16. rIhis hattened form is secured 4by the conjoint.and the yair currents entering through the apertures. 23, Q4, and theports 19, 2 0.' rl `hese' currents strike the iiame upon what become,under this action, its flattened sides, and 'those entering the portshaving' t-heform of jets and j enteringobliquely at considerablevelocity carry the lapex of theflame toa greater :height than wouldotherwise be secured.

They also insure'better combustion -adjacent the Wick end, `and retardthe formation of a crust bv more completely consuming, or at leastpreventing the condensationv of thev carbon. y

The burner producesa greaterillumination relatively to the oilconsumption than has been heretofore obtained, and insures a uniformityin the size and shape, and consequently in the' luminosity of thejlame,'for a very long period. y

I claim as-my inventionl; A lamp burner comprising, in combina-- "tion,a Wick-tube, an-oblong' cup mountedon .thetube and having its endsupwardly liaring andv ported adjacent their bases.

Q. A lamp burner comprising, 1n combina-A the tube and having its' endsupWardlyiiar-- ing and ported adjacent their bases, the side nalls'ofthe cup being cut away to-form V- shaped apertures.

.3. A lamp' burner "comprising, in combinzution, a Wick-tube, an oblongcup mounted on the 'Wick tube', the ends thereof seing scalloped andported in-theirouter lscallops adjacenttheii bases. 4. A lamp burnercomprising, 1n combination, a Wick-tube, an oblong cup mounted on the`Wick tube, the v'end sf'thereof belngl scallopedand ported-in theirouter scallo vs adjacent theirvbases, :the sidewalls of e los IiI

cup being cuiy away `t@ foei-:mdf-Shaped apen tures.

5. A lamp bums? omprisng'in combi'nw tion, a wick-tubs, and a, pair ofopposteydisposed mmng wmgif. extendlng upwardly Yfrom the end of thefflckiube, Such *wmgs being scalloped t@ 'm in each a central Channeland obque Walls a; ng the cham? ual, such wals bamgport-ed, ,.rjacentthe bases.
